Dikembe Mutombo signed a two-year deal with the Houston Rockets on Friday and plans to retire after the 2006-07 season.

"I don't see myself playing after this contract," the 39-year-old center said.

Mutombo's return gives the team a solid backup to All-Star center Yao Ming. The 7-foot-2 Mutombo is an eight-time All-Star and four-time defensive player of the year.

"In our opinion he was the best backup in the league last year," Rockets vice president of basketball operations Dennis Lindsey said. "He provided an immense number of wins when Yao was in foul trouble or we were struggling on the defensive end. Our locker room is a really special group of guys and Dikembe, being the elder statesman, is a leader in many of those aspects."
